Following her bronze in the single mogul format two days earlier, Cox maintained her strong form to win gold again and make it five podium finishes from the six World Cups this season.
Cox retained her yellow bib as the current world number one and remains focused on each event taking just one step at a time.
“I didn’t think it was going to pan out this way this season, I’ve just been focused on every event that’s coming, but it’s awesome to win again,” Cox said.
“The course was a lot more challenging tonight than it has been all week, but my family got to see me win for the first time which is really special.”
It was also a landmark personal best night for team mate Brodie Summers, who reached the World Cup podium for the first time by claiming the bronze.
Brodie Summers was impressive as he took flight on the way to a debut podium spot.
Speaking after his win in the Small Final, the 23-year-old shared his excitement.
“I’m so stoked right now, I was just having so much fun tonight and now I’m really on top of the world,” Summers beamed.
Summers raced against NSWIS teammate Matt Graham in the quarter final round on his way to the podium, with Graham finishing 11th overall.
“It was just great to ski with my boy (Graham) again, he had the tough line in that dual and I didn’t really know what was going on but he put up a really good fight,” Summers said.
Nicole Parks was the best placed of the remaining Australian female skiers finishing with a dual mogul PB in 8th followed by Krystle Yin (12th), Jakara Anthony (19th), Claudia Gueli (26th) and Madii Himbury (29th).
In the mens, James Matheson was 20th with Cooper Woods-Topalovic (24th) and Rohan Chapman-Davies (39th).
The next World Cup event for the mogul athletes is the Olympic test event in PyeongChang, Korea on February 10.
